For the time of operation Armtel equipment has shown the perfect efficiency and vitality in the chemically aggressive environment. We did not register any failures through the manufacturer’s fault. In practice we noted that the connection was reliable and of good quality. Armtel desks and intercom stations functioned properly in the conditions of high electric interference. I also would like to point out that at sites with the high noise levels the central operator could hear the subscriber (and vice versa) clearly and distinctly. This proves the well-considered schematic solution of intercom stations once more. »
